"Course outline is logical, content is great but the presentation videos are something to behold. Or not.  The presenters speak in a bizarre rambling vernacular that I find to be infuriating. Spent five year on a ChemEng BS and another two on a BiochemEng MS and NEVER once had to suffer through a lecture as messy as these ones. They are completely lacking in clarity and professionalism. Read the  transcripts of the viedeo lectures and you'll immediately see what I mean.  If english is not your first language you will be confused.  If it is your first language you will be frustrated. There are better online courses on data viz out there taught by genuinely intelligent and articulate professionals.  I'm looking forward to taking them after I complete this series of five sloppy courses.  In spite it all, I did learn a few basics and put them into practice and became familiar with a top-of-class BI viz tool. So, if you can slog through a few month of sub-amayure style teaching you just may learn someone but you'll have to be motivated to do a lot of self-directed learning."
